For many home gardeners, nothing is more frustrating than crop loss due to unknown causes. While vigilant
growers can closely monitor insect pressure in the garden which may cause diminished yields, losses due to unseen circumstances can be more difficult to diagnose. Gaining a better understanding of soil borne organisms and
pathogens can help growers develop a thorough grasp of soil and garden health.

All soil ecosystems contain various soil- borne organisms.
A soil borne pathogen is a disease-causing agent which lives both in soil and in a plant host, and
which will tend to infect undiseased plants which are grown in that soil.
The diseases that are caused by pathogens which persist (survive) in the soil matrix and in residues on the soil surface are defined as
soilborne diseases
Definisi
Soilborne diseases of ancient and modern agricultural crops have always had some impact on growth and productivity
Soilborne pathogens are readily spread if
infested soil or contaminated water moves into other fields or planting areas
Levels of soilborne pathogens, including bacteria, fungi, nematodes, and some viruses can be
reduced in the soil by appropriate treatments
Often these diseases are very difficult to manage due to their highly heterogeneous incidence and lack of knowledge on the epidemiological aspects of soilborne pathogens.
Soil-borne diseases in the garden include
- pre and post-emergence damping-off (like
Fusarium, Pythium and Rhizoctonia species) - root rot (including Phytophthora),
- vascular wilts (caused by fungi including Verticillium and nematodes).
The expansion in the crop diversity in agriculture has required parallel expansion of strategies to minimize the soilborne diseases.
The effective control/management of the soilborne diseases depend on:
- survival,
- dissemination
- effect of environmental conditions role of cultural practices
- host resistance and susceptibility
